Depiction in the series

Season two

Fancy Pants with Fleur Dis Lee

Fancy Pants first appears in Sweet and Elite when Rarity bumps into him and Fleur Dis Lee while walking through the streets of Canterlot. She instantly recognizes him as "the most important pony in Canterlot" and apologizes for running into him. He takes an interest in her when she mentions she is staying at Canterlot Castle by an invitation from Princess Celestia and invites her to his private box at the upcoming Wonderbolts Derby. He becomes more interested in Rarity after she correctly predicts the winner of the derby, and insists that she must be extremely important after she lies about knowing the trainer of the Wonderbolts, which she claims is Rainbow Dash.

He is featured in Rarity's song montage, as well as in many of the social events. He also appears in a flying yacht, wearing a captain's uniform.

Later on, Fancy Pants greets Rarity at a garden party next to the room where Twilight Sparkle's birthday party is taking place. Rarity's friends crash the event when Twilight "realizes" that Rarity wants to attend it, and subsequently offend many of the upper class ponies with their raucous partying. While Twilight is dancing to music, Fancy Pants stops her to ask about the dress she is wearing, which Rarity had made but never finished. Twilight proclaims Rarity as the designer, and Fancy Pants is again favorably impressed with her. He comments that "every mare in Canterlot will be wanting one," showing his influence when other ponies accordingly begin to say that they would like similar dresses.

Personality

Fancy Pants doesn't take much interest in Rarity until he learns she is staying at Princess Celestia's castle. He then invites her to the Wonderbolts derby and declares Rarity his new favorite party guest after she correctly predicts the winner and tells him she knows the Wonderbolts' trainer. He also expresses an interest in Rarity's simple, half-finished dress that Twilight was wearing for her party, even before he knew that Rarity had made it. He finds Rarity's friends "charmingly rustic" even though Jet Set and Upper Crust initially dismiss them.
